The first would be to make the item under "Training Topic" the link. That
way you have a descriptive idea of what you're downloading. This is my
preferred solution to allow everyone a better idea of what they're getting,
though they'll be missing the "How to" part.

The second option is to make the links longer where they are to include to
descriptive text, but this might break the existing designs.

The third option, if sighted users aren't a concern, is to use some visibly
hidden text as part of the link, e.g., <a href="#">How to<span
class="sr-only"> sign in to HUB</span></a>.
